Connected to the upper ends of the horizontal arms of 'the bell cranks 48 are links 50, the upper ends of which are pivotally connected to the outer ends of hand levers 51, which are fulcru-.med at to the front sides of the members of thc A-frame 20.' (See Fig. 8.) The inner ends of the levers 51 terminate adjacent each other at the center of the loader, where they are conveniently reached for operation..

The mechanism for raising and lowering the screw shafts and posts located at the rear ends of the machine comprises a shaft 53, liournaled in suitable bearings arranged on the posts 33; and fixed on said shaft 53 is a pair of friction wheels 54 and a sprocket wheel 55.

A pair of shafts 56 have their inner ends Vlournaled in bearings 57 located on a portion of the frame at the rear end of the loader, and the outer ends of said shafts being journaled in boxes 58 which are arranged to slide vertically on the front faces of the posts 27 5 and fixed on these shafts 56 are friction wheels 59 which are adapted to engage with the friction wheels 54, and there being sprocket wheels 60 fixed on said shafts 56 which are connected with the sprocket wheels 39 by sprocket chains 61.

Pivotally connected to the upper ends of the sliding boxes 5S are the lower ends of links 62, the upper ends of which are pivotally connected to hand levers 63, the outer ends of which are fulcrumed to the posts 3S.

Journaled in bearings 64, on the left hand side of the machine, is a transversely arranged shaft 65, on which are fixed three sprocket wheels 66, 67, and 68. A sprocket chain 69 connects the sprocket wheels 46 and 67, and a sprocket chain 70 connects the sprocket wheel 66 with the sprocket wheel 55. Arranged on the frame of the loader, adjacent the rear end thereof, is a boiler 71, and located adjacent thereto, on the center of the loader, is an engine 72, on the main driving shaft of wnich is fixed a gear wheel 73. Immediately in front of the engine is located a transverse shaft 74, which operates in bearings suitably located. on the center sills 10, and on the right hand en d of this shaft is fixed a pinion 75. Arranged to slide on the opposite end of this shaft 711 is a sprocket Wheel 76, on the hub of which is formed clutch face 77 adapted to engage With a corresponding clutch face 78 foi-ined on the outer end of the shaft 74. The sprocket wheel 76 is nioved longitudinally upon the shaft 74 by a hand lev\r 7 9 fnleruined at its lower end and provided at its upper end with a latch 80 adapted to engage in suitably located notches in a rack 81. Connecting the sprocket Wheels 68 and 76 is a sprocket chain 82, and fixed on the shaft 74, between the sills 10, is a pinion '33, Fixed on the shaft 7e and ineshing vwith the pinion 7 3 is a gear Wheel Tfi short distance in front of the shaft 74, with its right hand end onrnaled in a fixed bearing S5, and its left hand end being jonrnale-zl in a sliding bearing 86, and which latter bearing is inovcd longitudinally by lever 87 fulerurned at its lower end to the sill 10, on which said bearing is inounted, the upper' end of said lever being connected to rod 8, which extends rearwardly to a point in front of the engine frame, and being pivotally eon-' nested at its rear end to handle 89, which is 1n turn pivotally connected vto a traine (See Figs. 1 1

i, 17, and 1S.) i ixed on the shaft S4 is a druin 91, on which Winds the hoisting cable A, and fixed on the shaft 84, adjacent the druni 01, is a gear wheel 92, Whirl adapted to inesli with the pinion 33 when sliding bearing 86 is inoved rearnfardiv to its liinit of inoveinent. Arranged iri to the right of the shaft S4, and oxtendinr between the right hand sills and 10, is a shaft 03, the right hand end of Whieh is naled in fixed bearing 94, and the left hand end being journaled in a sliding gearing 05, which is arranged for operation on the right .hand one of the sills 10 and said sliding bearing being actuated by a lever 06iulcruined at its lower end, and being connected at its upper end to a longitudinally disposed rod 97, whieh is, in construction and operation, identical with the rod 8S. Fixed on the shaft 03 is a winding drinn 0S, and adjacent thereto is fixed a gear Wheel 96, which is adapted to inesh with the pinion 75 when the sliding bearing is at its 'rearward li. f movement. Adapted to Wind on the d n 98 is a cable 100, which passes between a pair of grooved pulleys 101 arranged for operation on the right hand side the right hand center sill 10, and carried by the end of said cable is a hook 102 Whieh is adapted to slide a gear Wheel 105, and which is adapted. to inesh with the pinion 73. rThe hub of the gear Wheel 105 is engaged by the yolre 106 of a hand lever 107 fulcrunied at its lower end, and provided at its upper end with latch 10S, which engages in suitably located notches forniedA in a rack 100. (See Fig. 16.) dournaled in suitable bearings, immediately to the rear of the shaft 103, is a shaft fili), on which is iixed a pinion 1 11, with which inesli es the gear Wheel 105 When the latter is in niesh with the pinion 73. Fixed to the left hand end of th fshaft 110 is a gear wheel 112, whieh, when the leader franie is lowered into position on the ear ada ted to carry the y loader nie/shes with the Oear wheel 6. ,f f o 84 designates a shaft which positioned a rlhe operation of our improved loader is as olloivs: vWhen it is desired to drive the oader with a series of einpty flat cars to the ooint vfiere said flat ears are to be loaded with logs, vthe loader occupies its nornial position upon its ear body, With the gear Wheels 6 and 112 in in esh, and With the sliding boxes 8.16 and 95 moved to their forward liniils of inoveinent, thus disengaging` the Wheels 92 and 99 frein the pinions 83 and 75; and with the sprocket vWheel 7 6 moved so as to disengage the clutoh face 77 from the clutch face 78. The hand lever 107 is now manipulated to throw the gear Wheel 105 into inesh with the pinions 111,' and, .vlien the engine is started, the rotary inotion of the engine sh aft is transmitted by ineens of the meshing gears and pinions 7st, 73, 105, 111, 112, and 6 to the shaft 45 and from thence to the car axle by the sproelret chain 8; and, in this manner, the loader and ernpty cars are driven along the track. to the point desired. 'Vilhen t ie point has been rear-hed Where the logs are to be loaded, the posts 27 are lowered to the ground and. the loader freine is raised on said posts to allow the einpty cars to be drawn beneath the loader fraine in the following manner: The gear Wheel 105 isdiseonneoted ,frein the pinions 73 and 111 by actuating the hand lever 107, after which the sprocket Wheel 76 is shifted on the left hand end of the shaft 74C so as to bring the cluteli faces 77 and 78 together. The engine is now starte-d and the rotary motion of the engine shaft is transmitted to the shaft 7 fi by ineans of the gear Wheel 7411, and the sprocket Wheel 76, rotating With the shaft 711, owing to an er-ageinent of clutch faces 77 and 78, drives the sproelret eliain 82 and rotary inotion is thus inii'iarted to the shaft 65. ln turn rotary motion is imparted to the shafts A and 53 by ineens of the sprocket chains 69 and 70, Wliioh eliains pass respeotively around the sprocket Wheels 67 and d6, and 66 and 55. {perators stationed at each end of the loader frame new manually engage tz e han d levers 51 and 63 and pull downwardly thereon, Whieh action, by means of the various connections, causes the sliding boxes 43 to move forward, and at the same time the sliding boxes 58 are moved downward, thus causing the pair of friction wheels Ll5 to be brought into engagement with the pair of friction wheels 42 5 and in a like manner the friction wheels 59 will be brought into engagement with the friction wheels The rotary motion thus imparted to the shafts Ll() is transmitted to the shafts 35 by means of the meshing pinions 37 and 41, and. the rotary motion of the shafts 56 is imparted by means of the chain 61 to the shafts on which the sprocket wheels 39 are i'ixed, and which last mentioned shafts drive the beveled gearing utilized for raising and lowering the rear pair of screw shafts 31. The beveled pinions 34 drive the pinions 33, and the same operating on the screw shafts 31 cause the same to move downward through the boxes 32 5 and following this action, the posts 27 are likewise moved downward through the loops 2r. The operators by properly manipulating the han d levers 51 and 63 can throw in and out the friction driving gear as desired, thereby accurately controlling the lowering of the posts 27 5 and when the frame of the loader is elevated, it can be brought to a perfect level by the proper manipulation of the handles. When the blocks 30 engage on the ground at the sides of the trash, the further downward movement of the screw shafts 81 and posts 27 will cause the body of the loader to rise from its car body and be elevated to such a distance as that said car body and the empty logging cars can readily be moved beneath the frame of the loader.

After the loader has been elevated to suliicient degree, the handle 79 is manipulated to shift the sprocket wheel 7G, thereby disengaging the clutch faces 77 and 7S, thus throwing the elevating mechanism out of operation, and the hook 102 is now carried to the rear end of the loader car and engaged thereon. The log hoolrs B, at the lower end of the chains C, which are detachably carried by the ends of the hoisting cable A, are now carried forward to the forward one of the empty cars and in so doing, the cable A will unwind from. the drum 91. The hooks are engaged on the forward one of the empty cars, and the operator on the loader now brings the handle S9 rearward to its limit of movement, thus imparting a corresponding movement to the rod 8S, and moving the journal bearing 86 rearward until the gear wheel 92 meshes with the pinion 83. The operator now starts the engine, and the rotary motion imparted to the shaft 7 -t is in turn imparted to the shaft S4 and drum 91, and, as the same rotates, the hoisting catle A will be wound thereon; and, in so doing, the empty cars will be drawn along beneath the loader from the front to the rear until the forward one of the ears is in a position immediately beneath the boom 21; and, during this action, the l cable 100 will unwind from the drum 98 and l lie immediately on top of the loader car and empty logging ears which are now to the rear of the loader. The hooks B are now detached from the forward one of the empty cars, and the boom 21 is swung to one side of the track or the other' in order that said hooks may be readily engaged on the ends of a log lying upon the ground alongside the track. lf the log be located some distance away from the track, the engineer may reverse the engine so as to permit the drum 91 to rotate in the proper direction to allow the cable A to unwind therefrom during the time said cable is drawn toward the log. After the hooks B have been engaged in the ends of the log, the 'operator starts the engine so as to wind the cable upon the drum, and the log will be drawn toward the first empty car; and, after being elevated thereover, is allowed to lower in position thereon. The post 18 and boom 21 of the derricl readily swing from one side to another; and, in so doing, the block 16 rotates upon the plate 13; and when a portion of the cable A extends sidewise from the outer end of the boom 21, it will bear on the rollers 26, which prevent the boom at the sides of the opening 25 from becoming worn.

1When the proper number of logs have been loaded on the first car, the operator shifts the sliding box 86 by actuating the handle 89, thus disconnecting the gear 92 from the pinion S3, after which the sliding box 95 is drawn to its rearward limit of movement by actuating the handle connected to the rod 97, which action brings the gear wheel 99 into mesh with the pinion 7 5. rThe engine is now started, and the rotary motion imparted to the shaft Q3 causes a portion of the cable 100 to wind upon the drum 98, which action moves the loaded away from its position in front of the loader, and brings an unloaded car into position to be loaded. These operations are continued until all of the empty cars are loaded, and iinally the loader car is brought into position immediately beneath the loader, and by properly manipulating the friction driving gear, the loader frame is allowed to lower onto the loader car; and the continued movement of the raising and lovering mechanism elevates the screw shafts 31 and the posts 27 until the blocks 3() are a sui'licient distance above the track.

lh/hen the loader is lowered onto the loader car, the gear wheel 112 meshes with the gear wheel 6 g and when 'the various parts are properly positioned and the engine started, the loader and the train of loaded cars are moved along the track to the point where the logs are to be unloaded. By arranging each vpair of screvY shafts 31 and posts 21 to move independently, the body of the loader can be l elevated and brought to a level positiony l regardless of the unevenness of the ground on which the blocks 30 engage. The blocks 3() at the lowerI ends of the posts 27 occupy positions entirely outside the ties of the track; therefore giving a broad base for the loader' to stand on while in operation, and the boom 21 can he readily swung from one side of the traclr` to the other, thus readily loadingl from both sides of the track.

Wvhile our improved apparatus is particularly adapted for loading logs, it will he readily understood that stone, utilized for buildingI purposes, and earth, sand, or coal, may he readily loaded onto the flat cars, and, where small material is so loaded, it will be necessary to arrange a suitable container' on the end of the hoisting cable A.

Thus it will be seen how we have provided an improved apparatus which handles a logging train with comparative ease, without the use of a locomotive, brinOs the empty cars into position to be loaded, and very rapidly lifts the logs from alongside the track and positions the saine on the cars.
